Description

Technical Field

[0001] This utility model relates to the field of dental impression manufacturing equipment, and more particularly to a device for manufacturing stable and accurate dental impressions. Background Technology

[0002] Dental impressions are a crucial step in dental treatment. They involve using specialized materials to obtain precise copies of teeth and surrounding tissues. This copying process is essential for the fabrication of dental restorations and orthodontic appliances such as dentures, crowns, bridges, and orthodontic brackets. Dental impression fabrication equipment typically refers to the tools and devices used to create dental impressions, which help dentists or dental technicians accurately replicate the shape of teeth and surrounding tissues.

[0003] Currently, dental impression making devices can be used to create precise models of teeth, facilitating dentists' diagnosis, treatment planning, and fabrication of dentures, crowns, and bridges. Existing stable and precise dental impression making devices use magnetic tracks and magnetic blocks with two magnets of opposite poles, allowing them to attract each other. The magnetic track is positioned to correspond to the area of ​​the missing tooth, and its length is determined by the extent of the missing tooth. The connection between the base plate and the magnetic track can be achieved by direct welding or other methods, with an insert block on the underside of the magnetic track that fits into a hole in the base plate. However, when inserting the device into the cavity, the impression tray may shift during impression taking due to involuntary muscle movements or swallowing reflexes. This can affect subsequent assessment of the patient's oral condition and may lead to misalignment of the denture edges with the gums, impacting the stability and comfort of the denture.

[0004] Therefore, it is necessary to provide a new device for manufacturing stable and accurate dental impressions to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a device for manufacturing stable and accurate dental impressions.

[0006] The present invention provides a stable and precise dental impression manufacturing device, which includes a handle, and a stabilizing component is fixedly connected to the bottom of the handle;

[0007] The stabilizing component includes a fixed base, a movable column, an adjusting block, and an adjusting mechanism. The fixed base is fixedly connected to the bottom of the handle, and a fixing hole is provided at one end of the fixed base. The movable column is rotatably connected to the inner wall of a through hole at the end of the fixed base away from the fixing hole. A limit block is fixedly connected to one end of the movable column. Both adjusting blocks are fixedly connected to the outer surface of the movable column. The adjusting mechanism is fixedly connected to one side wall of the adjusting block.

[0008] Preferably, the adjusting mechanism includes a fixed housing, a driving component, and a first threaded rod. The fixed housing is fixedly connected to one side wall of the adjusting block, the driving component is fixedly connected to one side wall of the adjusting block, and a second threaded rod is fixedly connected to the output end of the driving component. A sliding housing is threadedly connected to the outer surface of the second threaded rod, and a sliding inner housing is threadedly connected to the outer surface of the second threaded rod. The sliding inner housing is movably connected to the inner wall of the sliding housing, and a fixing component for fixing is fixedly connected to one side wall of the sliding inner housing.

[0009] Preferably, the driving component is a servo motor, which is fixedly connected to one side wall of the adjusting block, and the output end of the servo motor is fixedly connected to one end of the second threaded rod.

[0010] Preferably, the fixed base and the adjusting block are provided with a communicating limiting groove at one end.

[0011] Preferably, a base plate is fixedly connected to one side wall of the handle, and both the handle and the base plate are made of polystyrene material.

[0012] Preferably, the handle and the base plate are integrally molded.

[0013] Compared with related technologies, the stable and precise dental impression manufacturing device provided by this utility model has the following beneficial effects:

[0014] The stabilizing components first push the movable column towards the fixed base, causing the limiting block to move. When the movable column loses its limiting groove, it rotates, causing the adjusting block and the fixed outer shell on the adjusting block to rotate. Then, the servo motor is activated, driving the second threaded rod. As the second threaded rod rotates, it causes the sliding outer shell on its own to slide along the fixed outer shell. The second threaded rod also drives the first threaded rod to rotate, causing the sliding inner shell and the fixing component to extend. Simultaneously, the fixing component secures the movable column to the patient's chin. Then, the movable column and the limiting block on the movable column are moved back into the limiting groove. This device reduces the probability of the denture edge not fitting properly against the gums, thus reducing the impact on the stability and comfort of the denture. Attached Figure Description
